Hi

 

Check why it is not conv.,

  • by add. substeps:

  • and/or run a modal analysis (any rigid body modes will indicate the issue).

 

Also:

One thing to do to resolve this is :

 

 

  • remove force
  • add displacement at force location and push it down in y say by 0.0005 m (Z=X= 0 m).
  • Look at the reaction at this displacement to get the force.

 

 

In this way the model should solve I hope and we can see how it behaves

All the best

Erik
